We've seen these log messages slow down the NameNode. > {code} > 2016-03-07 15:02:23,272 INFO org.apache.hadoop.ipc.Server: Socket Reader #1 for port 8020: readAndProcess from client 127.0.0.1 threw exception [org.apache.hadoop.ipc.RetriableException: Server is too busy.] > {code} > We already have a metric that tracks the number of backoff events. This log message adds nothing useful. > The IPC Server should also allow services to skip logging certain exception types altogether. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
